DWO1DT995 Weed Trimmer Head Replacement for Dewalt DCST922 DCST925 DCST970 DCST920 DCST991 DCST990 Cordless String Trimmer, Weed Eater Head with 0.080" Spool Line Quick Load Weed Wacker Head - 2 Pack

What It Is

This is a replacement trimmer head assembly designed for Dewalt cordless string trimmers. It accepts 0.080" line and uses a quick-load (bump-feed) mechanism, making it suitable for residential trimming of grass and light weeds.

Fitment & Compatibility

Check your model number before buying. This head fits Dewalt DCST922, DCST925, DCST970, DCST920, DCST991, and DCST990 trimmers. It is an aftermarket replacement, not OEM Dewalt. Measure the shaft diameter on your trimmer—this head fits standard 0.375" (9.5mm) shafts. Confirm your trimmer uses a standard threaded or push-fit mounting system; this head uses a universal adapter that works with most Dewalt cordless models. If your trimmer has a different shaft size or proprietary mount, it will not fit.

Key Things to Know

• Line loading: The quick-load feature works well, but some users report the line can jam if not wound evenly. Follow the arrow directions carefully.
• Durability: Plastic housing is adequate for light use but may crack if you hit rocks or concrete frequently. Not for heavy-duty commercial work.
• Installation: Removal of the old head requires a hex key or screwdriver to hold the shaft while unscrewing. No special tools needed for the new head—just screw on and tighten.
• Line included: Comes with pre-wound 0.080" line, but replacement spools are standard and easy to find.

Should You Buy It

This is a good budget-friendly option if you own one of the compatible Dewalt trimmers and need a spare head for light yard work. It’s easy to install and reload, but if you trim heavy weeds or bump into hard surfaces often, you’ll likely get longer life from the OEM Dewalt head.
